I just finished up a Treadproof class with Frank and Marc (I highly recommend it) where we did Weaponized Math out to 675 yards. I am having a problem getting any of my ballistic solvers to match my dope that we gathered. I am using Strelok, AB with a Kestrel, and JBM. I have my 600 yard dope spot on. 200-500 is only .1 to .2 off which isn't necessarily much but I would like to know if it can be brought to being exact. So for the other part of my data, 650 and 675 is .2 mils off of my actual used dope. I went ahead and filled out the rest of the sheets try dope and found my software to be back within .1 to spot on. Now is this a case of only getting a chance to use this to 675? Do I need to take this out to 1000 to clean up my data?
